PCK3807ADB,112

Clock Buffers, Drivers Overview

The PCK3807ADB,112 is a 1:10 LVTTL clock distribution device manufactured by NXP USA Inc. (formerly Philips Semiconductors). It provides low skew clock driver functionality with a single input and ten outputs to reduce loading on preceding drivers. The component operates from a single 2.5 V or 3.3 V supply voltage over the industrial temperature range of –40 °C to +85 °C. Key electrical parameters include an input capacitance of 2.5 pF typical, output capacitance of 5.5 pF typical, and propagation delays ranging from 1.3 ns to 4.5 ns depending on load conditions. It supports operation up to 150 MHz with low power consumption.

Clock Buffers, Drivers Feature Summary

• 1:10 fan-out capability for efficient clock distribution
• Low output skew of 0.12 ns at 150 MHz with AC termination
• Operates on single 2.5 V or 3.3 V supply
• Industrial temperature range (-40 °C to +85 °C)
• Low input capacitance (2.5 pF) with hysteresis for noise immunity

Clock Buffers, Drivers Applications

• Clock and signal distribution networks
• LVTTL logic systems requiring high fan-out
• Industrial equipment operating in wide temperature ranges

Clock Buffers, Drivers Procurement Notes

Verify the ordering code PCK3807ADB corresponds to the 20-Pin Plastic SSOP package (SOT339-1). Confirm the suffix ,112 matches the manufacturer's reel packing specification. Check for current production status as datasheets may reference superseded versions.

Clock Buffers, Drivers Selection Notes

Select this component when a single LVTTL source must drive ten loads with minimal skew. Ensure the system operates within the 2.3 V to 3.6 V supply range. Verify that the 150 MHz maximum frequency meets timing requirements. Consider the 20-pin SSOP package dimensions if board space is constrained.

Clock Buffers, Drivers Part Context

This part belongs to the PCK3807A family of clock distribution devices. Other variants include the PCK3807AD (SO package), PCK3807APW (TSSOP package), and PCK3807ADS (QSOP package). All share identical electrical characteristics but differ in physical packaging.

Clock Buffers, Drivers Replacement Considerations

Direct replacements are limited to other packages within the same PCK3807A family (e.g., PCK3807AD, PCK3807APW) due to pin-compatible design. Cross-brand equivalents require verification of LVTTL compatibility and skew specifications.
